ADJUSTING DEVHTE IFC H T0 alt whom it may concern Be it known that I,Vrc'ron R. Koontrz, a citizen of the United. States, residing at l iaynesboro', in the county o'l. l 1:*anklin and State of Pennsylvania,have invented a new and useful Adjusting Device for Cutter- IEieads, ofwhich the following is a specification. i i

The present invention relates to iniiprovements in adjusting devices forcutter heads. the present device being particularly applicable tothestructure or cutter head shown in my UL S. Letters Patent No. 1,072,197,granted September 2, 1913, and one object of the present invention beingthe provision of a means whereby the tool operating member 01 the cutterhead may be minutely adjusted for its movement, such adjusting devicebeing disposed for ready action upon the ezeterior or peripheralportionof the main carrying member of the cutter head. and such adjustmentbeingreutlily observed and under the direct control of the operator at alltimes.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinet'terdescribed and claimed, it' being ui'iderstoed that changes in theprecise embodiment of the invention herein disclosed can be made withinthe scope of what is claimed without departing from the spirit of theinvention.

In the drawings: Figure 1 is a plan view of the cutter or tool carryingmember minus the tool or cutter carrier, the dotted lines indicating thepositionofthe respective parts 01 the adjusting device for regulatingthe said cutter or tool carryingmember relatively to the main carryingmember of the cutter head. Fig. 2 is a plan view of the carryingmel'nber showing the recess within which the main adjusting device ismounted. Fig. 0

shows a portion of the periphery oft such member showing the adjustingdevice for controlling the tool carrying member. Fig. i is a similarview showing the present adj usting device at the operating end thereotFig. 5 is an enlarged detail view illustrating the recess formed in thetool or cutter carrying member for the reception of the adjust ingblock. Fig. 6 is a detail view of the member for controlling theadjusting block. Fig. 7 is a detail. perspective view oi the adjustingblock. Fig. 8 is a section taken on Application filed March 21, 1913.

line S-tl of Fig. 1. Fig. 1;) is a section taken on line Sl t) o't l ig.1.. Fig. 10 is a diametrical section through the complete cutter head oithe aforementioned patent with the present invention appliedf Fig. 11 isa. :lront elevation of a portion of such cutterhead with the cutter ordie holders in work engaging position.

inferring to the drawing, the numerall designates the main tool. or dieholder carrying member which is a Hanged disk and has disposedtherewithin for oscillatory movement, as will presently appear. the toolcon trolling disk 2, which as shmvn is prov'hled with a. plurality ofeccentrically curved slots El for the reception of the inner end of thetool carrying posts or bolts Z). Upon i s outer face is mounted formovement into and out of workengaging position, the toolor die holders0, each carrying a tool or die d. The slots 3 are so arranged as tocause the movement of the bolt or bolts 7) nearer to or iarther from thecenter oli the member 1. to thus limit the movement of the bolts Z) andconsetpiently the cutting end of the tools (Z so that various sizedstock may be operated upon.

The disk 2, as clearly shown in Figs. 1 and Si, is n'ovided with aneccentrically as posed recess l: for the reception of the op crating andadjusting block 5, the same being elearlyishouui in detail in Fig. 7 endbeing provided with an aperture (3 :lorthe rece itimi ot the pin 13 ofthe operating block 12, the purpose of which will presently appear.Formed eccentrieally through the body of the member 1 and entendin froma point openii'ig at the center thereof and through the periphery is arecess and bore consisting of the enlarged portion 7, the nut receivingportion ti, and the screw receiving journaling aperture 9, and thecontrolling head receptacle ll, said receptacle ll being open throughthe periphery ot the member 1 as clearlyshown in lligsf-l and i. Theblock 12-, illustrated in Fig. e, is mounted for sliding movementwithinthe enlarged mrtion 7 of the recess of the member-ll, and is providedwith the screw threaded aperture or bore 14 theretln'ough for thereception of the operating screw 15. said screw 1:3, as shown in llig.1, being journaled in the portions 9 and 10 oi the slotted portion oi?the member l, and being retained against outward movement by means ofthe locking nut 16 seated within the recess 8.

Seated within the recess 11 and fast upon the outer end of the screw 7,is a bushing or sleeve 17, which is held in place by means of theshouldered end 18, or both the bushing 17 and shouldered end 18 may beformed integral with the screw 15, the outer pe-- riphery oi the sleeveor collar 17 being provided with the scale 2%, which is disposed tocooperate with the scale carried upon the flange of the member 1 asclearly shown in Fig. 4, so that the screw may be operated and theadjustment of the block 12 controlled thereby, be indicated by suchscales, and as the said block 12 is operably con-- nected to the block5, said block is moved in its slot 1 according to the position of theblock 12 upon the screw 15. By this means the disk member 2 isoscillated within the flange portion of the member 1 and according tothe desires of the operator. By this means it will be seen that theposition of the slot 3 relatively to the post Z) and the radial slot 1of the member 1 will be ad justed and thus the consequent throw of thetool or die holder 0 will be controlled by the simple manipulation ofthe screw 15 through the shouldered end 18 thereof.

In order to provide a means for locking the tool actuating disk 2relatively to the carrying member 1, the rim of the carrying member asshown in Fig. 3, is slotted circumferentially as at 19, for thereception of the clamping block 20, by the aneans of the screw 21 whichprojects through the block and engages the tool actuating plate, Fig. 8.The scale 22 is carried by the block and its coacting scale 23 iscarried by the rim or flange of the member 1 so that the adjustment ofthe block 20 relatively to the flange of the member 1 maybe regulated toan exactness and indicated by the gage or scale as herein shown.

lVhat is claimed is:

1. A cutter head, including adie carrier actuating disk, said diskbeing. provided with a tangentially disposed recess extend mg from apoint near its center to its pe riphery, a block slidably mounted insaid recess, a supporting disk for the actuating disk and in which saidactuating disk is mounted for oscillatory movement, and a screwjournalcd tangentially within the last disk and in angular relation tothe recess of the first disk for operating the block to adjust thecarrier disk relatively to the supporting disk.

2. A cutter head, including a die carrier actuating disk, said diskbeing provided with a recess extending from a point near its center toits periphery, a block slida-blymounted in said recess and projectingbeyond the face of the disk, a supporting disk for the actuating diskand in which said actuating disk is mounted for oscillatory movement,and a screw journaled within the last disk and embracing the projectingportion of the block, whereby as the screw is rotated, the die carrieris moved relativel to the supporting disk.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
